Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention supplies water contained in a water tank to a vaporization chamber of a base through a communication hole provided at the bottom of the water tank, and the steam is generated in the vaporization chamber. The present invention relates to a steam iron.

(Prior Art) Conventionally, a steam iron supplies water in a water tank to a vaporization chamber of a base by natural fall through a communication hole provided in a bottom portion of the water tank, and steam generated in this vaporization chamber is stored in the base. The structure is such that it spouts from the steam hole through the steam passage.

However, in such a structure, since the water supply to the vaporization chamber is caused by a natural fall, when the water level in the water tank decreases with time, the head pressure decreases, the drop amount decreases, and the steam ejection amount decreases. There was a problem that the steam could not be supplied stably because the amount of steam decreased or the steam temporarily stopped breathing.

Therefore, conventionally, for example, as described in Japanese Utility Model Application Laid-Open No. 59-16598, a first space chamber and a second space chamber in which a communication hole communicating with a vaporization chamber is formed inside a water tank. When the partition plate that is vertically partitioned is erected vertically, and the first and second space chambers are communicated with each other on the upper side of the partition plate, and when this steam iron is in the standing position,
A steam iron having a structure in which water in the second space chamber flows into the first space chamber and water can be sufficiently supplied from the communication hole to the vaporization chamber has been proposed.

Further, as described in Japanese Utility Model Laid-Open No. 57-27297, water contained in a water tank is supplied to a vaporization chamber of a base through a communication hole provided at the bottom of the water tank, and steam is generated in the vaporization chamber. In the steam iron configured to generate the above, in the inside of the water tank, a front side space chamber provided with the communication hole and a rear side space chamber communicated with each other at a communication portion formed at a lower portion of the front space chamber are provided. A steam iron with a different structure has been proposed.

(Problems to be Solved by the Invention) In the steam iron having the structure described in Japanese Utility Model Laid-Open No. 59-16598, the water moves only when the steam iron is set up, so the water level during use is If it decreases, the hydraulic head pressure to the communication hole may become insufficient, and despite the relatively large amount of water remaining as a whole, the hydraulic head pressure to the communication hole becomes insufficient and the steam supply becomes unstable. There is a problem that it may become.

In the steam iron having the structure described in Japanese Utility Model Laid-Open No. 57-27297, water is stored in the rear space of the water tank when the iron is self-supporting, and the water is stored in the horizontal space of the iron from the rear space to the front. Water flows into the space chamber, and the head of the front space chamber is held so as to be on the upper surface of the communicating portion so that the head can be made substantially constant.

However, in the steam iron with this structure, when the water surface falls below the upper end of the communication part, the water head pressure drops sharply, the amount of steam ejection decreases, and the steam temporarily breaks, causing a breathing phenomenon and stabilizing the steam. There is a problem that can not be supplied.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a steam iron that can always stably supply steam.

(Means for Solving Problems) The steam iron of the present invention supplies the water contained in the water tank to the vaporization chamber of the base through the communication hole provided at the bottom of the water tank, and the steam is generated in the vaporization chamber. In the steam iron that is generated, a partition body for partitioning the first space chamber and the second space chamber having the communication hole is provided inside the water tank from the inner bottom surface of the water tank to the first space. The partition is provided so as to be inclined upward toward the chamber, and a communication portion that communicates the first and second space chambers with each other is provided on the upper side of the partition body.

(Operation) In the steam iron of the present invention, the water in the second space chamber easily crosses the partition body inclined in the first space chamber direction by the reciprocating movement at the time of ironing the first space chamber. On the other hand, the water in the first space chamber does not easily flow into the second space chamber due to the partition body, and raises the water level in the first space chamber having the communication hole, resulting in insufficient head pressure for the communication hole. And the supply of steam does not become unstable.

(Embodiment) Hereinafter, a configuration of an embodiment of the present invention will be described with reference to the drawings.
